members 52 are spaced suificiently apart so that the bar 22 may be placed on the beveled ends-23 adjacent end of the second bar and means carried by each U-shaped member for applying pressure on the second bar, whereby to cause the second bar to press the overlapped ends of the sheet of material against the longitudinal bar.

2. A device for forming a sheet of materal into a protective sleeve, the opposite ends of the material being beveled, comprising an oblong base,

supports on the base at opposite sides thereof, a

post rising from each end of said base, a bar supported by the posts midway between the side "supports, a retaining means pivotally mounted on and 24 of the material 25. The members 40 and Q 42 are for the purpose of retaining the ends in position so that the clamping bar 22 may be applied to the beveled ends of the material.

A coil spring 54 is attached to the under-face of each member of] and 42 and extends downwardly and is connected to a lug 55, mounted on the base It.

The operation of my device is as follows:

Before the material 25 is applied to the machine, the bar 22 must be removed'after the yokes 30 have been swung beyond the ends of the bar 2|. out of position so that the handles M are depressed until the catches 45 engage the pins 46. The end 24 of the material 2 is placed on the flat surface of the bar 2!, after which the catch 45 is released so that the spring 54 will pull the inner end of the member All downwardly and engage the end 24 and retain it in position on the bar 20. The other catch 45 is released so that the spring 54 will pull the inner end of the member 42 downwardly and engage the other end 23 of the strip of material 25. In this manner both of the ends 23 and 24 will be positioned on the bar 2!, with the beveled edges on the ends of the strips 25 being in overlapping position. Cement is then applied to one beveled edge or both beveled edges if necessary..

. The clamping ends 23 and 24 of the material 25 are now held in place so that the bar 22 may be applied to the cemented ends of the material. The yokes 30 are then swung inwardly so that the free ends of the threaded bolts 32 may slip over the rounded ends of the bar 22 and engage the upper surface of the reduced portions 26 of said bar. If necessary the knobs 34 may be manipulated to exert pressure on the bar 22, so that the beveled edges of the material 25 will be held firmly in place to permit the cement to dry, which only requires a few minutes.

As soon as the ends are cemented together, the operating arms 44 are moved downwardly until the catches 45 engage the pins as, whence the members 4!} and 42 will be held in an inoperative position. The bar 22 is then removed by the release of the yokes 30, after which the bar 2| is raised from the sockets 2B in the upper ends of the posts l3, and the completed sleeve is then slipped ofi' said bar, after which other sleeves are formed on the machine.

What is claimed is:

1. A device for forming a sheet of material into a protective sleeve with the opposite ends of the sheet being beveled, comprising a frame, a longitudinal bar mounted on the frame, a clamp pivotally mounted at each side of the frame and having an inner free edge adapted to retain the beveled ends of the sheet in overlapped position after one of said ends has had an application of cement, a second bar resting on the overlapped ends, a. U-shaped member pivoted on each end of the first-mentioned bar and swingable over an The members M) and iz must be moved the supports at each side of the base and provided with a straight edge adapted to maintain the beveled; ends of the sheet on the bar, with the least one edge has had an application of cement,

- supported by the posts midway between the side supports, -a retaining means pivotally mounted on the supports at each side of the base and provided with a straight edge adapted to maintain the beveled ends of the sheet on the bar, with the beveled edges-0f the material overlapped after at least one edge has had an application of cement, a second bar resting on the overlapped ends, springs holding the retaining means pressed on the material, and a threaded bolt swingably mounted on each end of the first bar and adapted to exert pressure on'the second bar, whereby to cause the second bar to press the overlapped ends of the material against the first-named bar.

4. A device for forming a sheet of material in- :to a protective sleeve with the opposite ends of the sheet being beveled, comprising a frame, a

longitudinal bar mounted on the frame, a clamppivotally mounted at each side of the frame and having an inner free edge adapted to retain the beveled ends of the sheet in overlapped position after one of said ends has had an application of cement, a second bar resting on the overlapped ends, the longitudinal bar being removably carried by the frame, springs holding the clamps pressed on the material where supported b the longitudinal bar, a U-shaped member pivoted on each end of said longitudinal bar, and a bolt threaded into a passage in thebight portion of each U-shaped member, and engageable with an adjacent end of the second bar for exerting pressure on said bar, whereby to cause the second bar to press the overlapped ends of the sheet against the longitudinal bar.
